A bit of cleanup in the inspector and suggestion code
A bit of cleanup in the inspector and suggestion code

* function() -> function ()
* ){ -> ) {
* Quoted JSON keys (Look the other way Timo!)
* Using more descriptive group names, which also avoid using "new" as a key
* Line breaks at 100 columns using 4 spaces/tab
* Not setting classes on suggestion items that have no effect (such as 'external' on a div - even on an <a> tag this isn't enough to get the style because it's not inside #content)
